Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to determine if lidocaine patches decrease post-operative pain associated with cesarean births. While the Lidoderm lidocaine patch has been FDA approved for the treatment of skin pain, it has not been studied in women undergoing cesarean birth who experience postoperative pain. Even though this medication has been used in post-operative pain in published studies, the use of this medicine under these circumstances is still considered experimental. A lidocaine patch may provide added benefit for pain control in addition to standard medicines participants would receive after surgery, such as spinal, intravenous, and oral pain medications following cesarean delivery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
12-hour Postoperative Pain Scores
Time Frame: Postoperative (12 hours)
To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 12 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".
Postoperative (12 hours)
24-hour Postoperative Pain Scores
Time Frame: Postoperative (24 hours)
To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 24 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".
Postoperative (24 hours)
36-hour Postoperative Pain Scores
Time Frame: Postoperative (36 hours)
To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 36 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".
Postoperative (36 hours)
48-hour Postoperative Pain Scores
Time Frame: Postoperative (48 hours)
To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 48 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".
Postoperative (48 hours)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
5-days Postoperative Narcotic Use
Time Frame: Postoperative (5 days)
To determine if narcotic use changes when patients use lidocaine patches by counting amount and frequency of narcotic use over admission. Average number of 5 mg oxycodone pills used in women who have undergone cesarean delivery assessed through questionnaire at 5 days postoperatively.
Postoperative (5 days)
